Changing service interval type (variable to fixed)

[mattpanton]

Is it fairly straightforward to change my 2001 1.9TDi A4 B5 from variable servicing to fixed? I guess this is a job for VCDS (hence posting in here). I have access to a cheap-o ebay lead and the trial version of VCDS, is the functionallity in this software or will I need the full blown jobbie and a proper lead?

Thanks
